有些分式方程，若按照一般的方法去解，往往需要进行繁琐的计算，而且有时还会出现难解的高次方程；如果注意它们的结构特征，用特殊的方法来解，则能化繁为简．下面介绍几种方法，供同学们参考：例１解方程：分析方程两边各自通分，原方程可变为所以（Ｘ＋２）（Ｘ＋４）＝（? Some fractional equations, if they are solved according to the general method, often require tedious calculations, and sometimes difficult to solve high-order equations; if you pay attention to their structural characteristics, using special methods to solve, you can For Jane. Here are some methods for students to refer to: Example 1 Solution equation: Analyze the equations on both sides of the respective points, the original equation can be changed to (X+2) (X+4)=(?
